4Be it known that I, J oHN'H. ELsrAss, a citif zen of the United States, residing in the city and county of Denver and State of Colorado,

have invented certain new and useful Improve-J ments in Rock-Crushers; and I do declare kthe following to bela full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsl to make and use the same, reference being had to the accompanying drawings, and to the. letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in rock-crushers, my object being to provide an apparatus of this class vwhich shall be efficient, reliable, and durable in operation as well as economical in cost.

In my/improved crusher the movable jaw` is hung from the top on an eccentric formed on the driving or operating shaft, while the lower extremity of the jaw has a link connection with the forward extremity of the frame.

This link connection consists of two shafts orf journals which engage bearings formed in the lower part of the movable jaw and a block, respectively. This block is vertically movable on the front of the frame, whereby the center of motion for the lower extremity of the movable jaw may be regulated at will.

Bythrowing the journal which engages the lower extremity of the movable jaw more or less below a horizontal line passed through the outer journal the lateral travel of the crushing-face of the jawor its back-and-forth movement at its llower end during the performance of the crushing action may be regulated at will. The movable jaw is further Y' supported by a rod which extends rearwardly the eccentric-bearing. It will thus be seenv that during the rearward and upward movement of the jaw the crushing material has a downward tendency, since the space within which it is confined is enlarged. It will also be observed that during the downward and forward movementof the jaw there is both a grinding and a crushing action, the tendency of this movement of the jawbeing also to drive the material downwardly.

By locating thev center of the vjournal which engages the lower extremity of the movable jaw below the horizontal line passed through the center of the outer journal of the link or tie-rod connection as the movable jaw moves upwardly it opens or moves away or rearwardly from the stationary jaw, while during the downward movement the movable jaw also moves forwardly or has the closing action. l

It will' be observed that the special constructionand arrangement whereby the jourlnal of the lower extremity of the movable jaw lmay b'e located at any desiredk distance v below the horizontal line above mentioned is important, since the jaws travel may be regulated by virtue of this adjustment.

Having briefly outlined my improved construction, as well as the functionit is intended to perform, I will proceed to describe the same in detail, referencev being made to the accompanying drawings, in which is illustrated an' embodimentthereof.

In the drawings, Figure lis a sectional view of my improved Crusher, taken on the line 1 1,

Fig. 3, showing the movable jaw at its upward limit of movement. Figj2 is a similar view showing the movable jaw at its .downward limit of movement, the driving-pulley and fly-wheel being omitted. Fig. 3 is a front view of the construction shown in Fig. l,- the fly-Wheel and pulley being partly broken away. Fig. i is a detail view of the link con' nection or tie-rod connection between the lower extremity of the movable jaw and thev l forward end of the frame.

The same reference characters indicate the same parts in all the views.

Let A designate the framework of the apparatus'. Between the sides A of this framework is located l the integral front part A2, against which bears the front wearing-plate or stationary jaw A3, which is held between` the two side wearing-plates Af. J ournaled in roo E the sides ot the frame is a shaft B, provided with an eccentric B', which engages an openingi'ormed in the upper extremity of the movable jaw C. The jaw is provided with a bushing B2, located above the shaft and held in place by a key B3. The face-plate B'l ot' the movable jaw engages a shoulderB' at its lower extremity, while its upper extremity is beveled and engaged by the head of the bolt B, whose outer extremity is threaded to receive a nut B7. The shape of the bolt-head is such as to lock the face-plate B1 in position when the nut is screwed tightly against the rear side of the jaw. The rear side of the jaw C is provided with a lug C', to which is attached a screw-eye C2, which is engaged by a bolt C3, which passes through a connecting-plate G1, forming a part of the frame. The outer extremity of this bolt is provided with a nut C5, and belowthe nut is a cap CG. Between this cap and the rear part of the frame is located a coil-spring D, which surrounds the bolt and is normally under tension, having a tendency to lift the movable jaw.

The rear side of the lower extremity of the movable jaw is recessed, as shown at E, to receive a journal E. whose outer extremities are enlarged, as shown at E2, and slotted to receive tie-rods F, which pass on opposite sides of the movable jaw and protrude from the front part ot' the frame. A shaft or journal Gr, similar to E, is provided with enlarged heads Gr, through which tie-rods F also pass, the said heads being slotted to receive the rods, rIhis shaft or journal G engages a recess formed in a block H, slidably mounted between parts H, formed on the front of the frame. This block H is connected with a bolt H2, which passes through a lug H3, formed integral with the frame. To this bolt is applied an adjusting-nut Hf, located above the lug, and the lock-nut H", located below the lug. It is evident that by virtue ot' this adjusting-bolt the block H, and consequently the journal G, may be raised and lowered at will. By virtue of this adjustment the relative arrangement of the shaft or journal E with ret'- erence to a horizontal line I, passingthrough the center of the journal Gr, may be regulated at will. rIhe farther the journal E is below this line the farther will be the travel rearwardly and forwardly of thelower end of the jaw during the rotary movement ot' the eccentric driving-shat't B, as will be readily understood. It will also be understood that by keeping the journal E/ continuously below the horizontal line I the travel of the lower extremity of the movable jaw will always be away from the stationary jaw A3 during the upward movement of the movable jaw, while during the downward movement of said jaw the lower extremity of the jaw will be toward the stationary plate A3. It is evident that it' the journal E/ were raised above the horizontal line I that the reverse of the forei going result wouldbe true. Attention iscalled to these points in order to indicate the ad vantages ot' the capabilities ol' adjustment which my improved mechanism possesses.

The curved dotted line .l is the arc ol a eircle struck from the center of the journal i. As the mechanism isarranged in thedrawings the center of the shaft or journal IC will always b e below the intersection olE the lines l and J, and it is believed that the best results will be obtained when these conditions exist, l'or the, reasons heretofore stated.

The journals or shalts (i and IC' are properly spaced on the tie-rods by means ol pins K, passed through both extremities olt the tie-rods outside ofthe enlargements It and tl.

Tashers K2 may be employed between the pins K and the parts (i in order to regulate the space between the stationary and un Yable jaws, which it is evident may be regulated at will. The pins K are of such size that the are brealiable or adapted to be sheared oll` in case an object of unusual hardness passes between the two jaws of the Crusher, whereby the breakage ot' important parts ol the mechanism is prevented.

In the drawings I have shown a ily-wheel L and a driving-pulley M, mounted on the driving-shaft B. It is evident that the machine will be operated by applying power to the shaft B. During` the rotation ol this shalt and by virtue of the eccentric l, which engages the upper extremity ot the movable jaw, as aforesaid, the said jaw is moved upwardly and downwardly and forwardly and rearwardly in a manner that will be well understood Jfrom what has already been stated.

Having thus described my invention, what I claim isWw l. In a rock-Crusher, the combination with a suitable frame and a iixed jaw, a movable jaw, means for imjiartinga circular motion to one end of the movable jaw, means lor causing the other end ot' said movable jaw to more, ou an arc whose center lies beyond the lixed jaw, and means for adjusting the center ol said are in a line substantially parallel with the lace of said iixed jaw.
